MSFS process frequently hangs forever after "quit to desktop"

Are you using Developer Mode or made changes in it?

no

Have you disabled/removed all your mods and addons?

no, I don’t want to use MSFS without my 3rd party planes and airports

Brief description of the issue:

Starting with SU11, when I try to exit the flight sim (using “quit to desktop”) after completing a flight, I’m back on the desktop, but the MSFS process will frequently get stuck. When this happens, the process is still running and visible on the Windows taskbar. I waited up to 10 minutes to see if it would finally shut down on its own, but it never does. “Close window” from the context menu does nothing. I have to restart Windows, use the task manager (“End task”), or the “Stop” button in Steam to force the process to quit.

Detailed steps to reproduce the issue encountered:

I don’t know how to reproduce this issue in a reliable way.

PC specs and/or peripheral set up if relevant:

Win10 on Ryzen 9, 3800ti (526.86), 32GB. I purchased on Steam. I’m flying in VR using SteamVR and OpenXR Toolkit.

Build Version # when you first started experiencing this issue:

I believe it started with 1.29.25 or 1.29.28.

hi, i saw and replied to your other thread. i do see this now “no, I don’t want to use MSFS without my 3rd party planes and airports”, but also “I don’t know how to reproduce this issue in a reliable way.”

gotta be honest, you’ll have to disable the addons and track it down one by one. i have this exact same issue, and by just narrowing it down, i know exactly what 3rd party files are causing it (even though i dont know exactly whats in those files yet that may be causing it)…i’m betting if you disable everything, or crash it yourself and boot into safe mode, it’ll be fine.

but if you know what the cause is, that’ll help both of us try to narrow it down better and report it to devs, either 3rd party or Asobo that can fix it.

I’m not a paid beta tester, I’m a paying customer. I have no interest in completing hour long flights in MSFS in default planes and default scenery just for testing.

In the past, I spent days debugging and nailing down issues, I wrote posts the size of novels both in the forums and on Zendesk, and all I ever got in response were boilerplate texts. Those bugs are still in the sim to this day.

I hope you understand when I feel that I’ve done what I can by reporting this bug. If my past experience had been different, I might be inclined to do more work. If anyone else wants to debug this for Asobo, they’re free to do so.

Removed my vote. For me it’s 3rd party conflict. Just verified by deactivating/reactivating my addons using addons linker.

Then you’re not helping anything by not disabling your addons. If you don’t want to do it one by one, i get it. But dont put the blame on Asobo if you’re not even trying to narrow it down between your 3rd party stuff or the vanilla sim at least somewhat.

You said you have planes and airports. In my case, its a set of airports, i pick any one of them, in any plane, sit in the cockpit for two seconds, and exit the sim to see if it hangs. And i’ve heard some freeware airports may have this issue…that’s all I’m saying

There is literally nothing an add-on should be able to do to keep the sim from shutting down properly.
I accept that you have a different opinion, I ask you to do the same.

Well I beg to differ. You literally have a comment before mine who did what I suggested and disabled everything, bam it works…Even just as I was typing here, I did some quick testing on my end. I narrowed down my problem even further to my 3rd party airport jetways specifically… So imma let the dev who made em know, because I took 5 minutes with Addon Linker and found it.

I’m building freeware airports for MSFS. As far as I’m aware, there is nothing I can do to an airport to influence how the sim behaves when it’s shutting down. The only exception would be to not use a feature that triggers a bug in the sim.

I appreciate that you reported it to the dev, though, because they might be able to raise the issue on the SDK forum. The Asobo people there are quite responsive.

PS: Would you disclose what the products are that trigger the issue for you? I don’t have many payware airports, but if there’s an overlap, I would definitely be willing to test a specific airport to provide an additional data point for that dev. Apart from that, I’m just gonna learn to live with the problem. I’ve verified that state saving doesn’t appear to be affected by the process getting stuck, so, for me, it’s now just a cosmetical issue, an inconvenience. Of course for many MSFS users I know it’ll be a source of frustration, because, believe it or not, many “non-power users” don’t even know about Task Manager.

I have a bunch of airports from SimAddons.com… Ralph there makes some great FSX ports for Canadian airports, but always keeps on top of updates. I imagine theres some old code in his jetways that other payware/freeware might have. He has a private support forum. I have a bunch of his stuff, any airport I bought from there (well, i guess with jetways specifically now) has the problem.

Someone said on that forum the freeware CYUL (which is way outdated) triggered it, but it didnt for me.

Edit: I have confirmed that other airports of his without jetways are fine. Something in the jetways are causing a memory leak (RAM wont ramp down after going into main menu, its double compared to other airports while exiting).

Thanks for the specific test case. I believe on my system, the only airport with jetways that’s in the region I was flying in recently is Punta Cana (MDPC) by Tropicalsim. I’ll try without that airport when I get the chance.

I still maintain that it’s a bug in the sim when the process doesn’t shut down because of an outdated or misbehaving piece of 3rd-party content. It’s a function of the sim engine to manage (as in: load and unload) content.

I’ve been testing against SierraSim MYNN Nassau which also has jetways, that one is fine. I also have numerous other jetway airports by various devs without issue (ini, FlyTampa etc)…Out of curiousity I went over to the GSX forum since that heavily modifies jetways and saw this recently - “when I try to exit the flight (in 2D) the sim just hangs on the loading screen. Deactivating GSX removes these issues.”

For the record I do not use GSX.

Also the only patch note in 11 I see relating to this is: “Fixed scenarios where jetway update were too slow”…whatever that means.

Neither do I. I can proudly state that, in close to 40 years of sim flying, I’ve never used a jetway. The only airliners I’ve ever flown came with their own set of stairs… and ashtrays.

I have the same issue since SU11. The game process sometimes gets stuck in an infinite loop using 100% of one CPU core when quitting the game. I can reproduce it reliably with the Kodiak aircraft, even if it’s the only active addon. A short pattern at an airport in the desert is enough to trigger the behavior after quitting the sim. That does not mean that it’s connected to the particular aircraft, though. I have not done any more testing. It also happened after flying the various new aircraft yesterday.

That’s a very interesting data point, thank you very much.

Putting my vote back in. Thought it was an addon but seems the issue is random.

Seems to only happen after VR for me. More testing required.

Fixed on my end. The author who made the 3rd party airports i bought which had the issue with jetways made an updated exe installer.

The only noteworthy thing it did was provide me with a AI.PC.PCK file under \SimObjects\Landmarks\jetways\soundai which was missing while the problem occured. Once i have it now, it quits fine.

I should note that his exe’s are safe but unverified according to Microsoft. So in recent Windows updates, they need to be run in admin mode with every anti-virus and/or defender option turned off during the install. I wanna say I did this last time i installed, but its possible I missed a setting. With that being said (for those having this issue with 3rd party content), if you’ve installed an exe from a 3rd party in the past few months in the latest builds of Windows, especially unsigned ones, and not in admin mode with AV protection turned on, you may be missing files causing this issue.

Do you have the same issue if you follow the OP’s steps to reproduce it?

YES

Happend till now two times since installing 1.29.28.0. I can kill it per Taskmanager. May be important to mention: the running.lock file seems allready removed , because I get no Dialog which ask about Safe-Mode in next start of MSFS.
No mods installed , and no issues otherwise ( no CTD ).

Happens randomly, not every time. No VR being used, only add-ons are planes from the marketplace. This issue didn’t happen before SU11.
